Helllo! So i just got a violet laser off of ebay but around the dot, there seems to be a ring like spill on a flashlight? Is there anyway to fix this? o_0 The dot seems very significant... like not a little maybe 6 inch diameter on the spill from 10 feet away? is this normal?Thanks!

Be careful cleaning the lens. Don't scrub it. STOP NOW.
Try that dusting gas in a can first. Don't blow into it -- for sure a glob of spit will mess it up. There are some threads on here about cleaning lenses.
I just got a $11 Blu from ebay and it's good at 45 mW !!
